CHURN.

To all 'whom t may concern 4 Be it known that I, Essex L. LoMAx, a citizen of the United States, `residing at Washington, in the VDistrict of Columbia, have invented certain new and useful lmprovements in Churns, of which the following is a specification.

lThis invention relates to the class of agitators, and more particularly to novel and useful Vimprovements in churns.

The invention relates more specifically t rotary churns, and to that class in which the rotating' blades, of which there are two in number, rotate in opposite directions so as to give sufficient agitation and expedite the churning` operation, the blades being con structed in a novel manner fo-r the purposes mentioned.

With the above and other objects in view, as will appear as the description proceeds, the invention comprises the various novel features of construction and arrangement of parts which will be more fully described herein and set forth with particularity in the claim appended hereto.

Reference is had to the accompanying drawings forming a part of this application, in which like reference characters indicate the corresponding parts throughout the sev.- eral views, in which Figure 1 is a vertical sectional view of an improved churn constructed in accordance with my invention,

Fig. 2 is a horizontal sectional view taken through the churn blades, and

Fig. 3 is an enlarged detail sectional view showing the manner of securing the outer churn blade in position.

Referring to the drawings in detail, the

numeral 10 indicates a container, preferably in the form of a glass jar having a screw to l1 u ion which the o eratin@ mechanism is supported and adapted to operate through a central opening 12 therein. Arranged upon this cap is a frame 13 having journaled horizontally therein a shaft 14 provided with a suitable operating handle 15 on its outer end.

At the inner end of the shaft 14 there is secured a large bevel gear 16 meshing with upper and lower bevel gears or pinions 17 and 18 respectively. The gear 17 is fixed to a shaft 19 rotatably journaled in the bearing part 2O of the frame and in the upper part of the latter, suitable means being provided t0 support the shaft against displace- Specification of Letters Patent.

directions.

The Adasher construction which comprises the particular novel feature of my invention, consists of an outer blade 22, having the upper end thereof split centrally and vertically thereof and received within opposite bifurcations 23 of a casting or the like 24 secured to the lower end of the tubular shaft 21. This blade is also provided with a tapered upper end produced by inclined side portions 25, the upper end of the blade 22 being thus tapered for attachment as specified, and provided with a similarly shaped central opening 26. The opening 26 terminates short of the bottom, so as to provide a transverse connecting strip 27, while the opposite edges of the blade 22 are curved in opposite directions, as shown at 28, and provided with adjacent series of openings 29 vertically arranged.

Received within the opening 26 is an inner blade 30, the same corresponding in shape to the outer blade and the opening 26 and being spaced from the inner edge walls of the opening 26 and having its upper tapered end secured to the split lower end of of the shaft 19, as shown at 31. This blade 30 has its opposite vertical edges curved in opposite directions as shown at 32, the curvature thereof being opposite to that of the curvature of the portions or vertical edges 28 of the outer blade 22, thus causing `the curved portions of the inner blade to throw the fluid against the curved portions of the outer blade, which latter will impart opposite motion or agitation thereto, to accomplish the churning operation efliciently and expeditiously. The tapered or beveled formation of the upper ends of the bladesalso prevents the splashing of the contents of the `iar against the cover thereof, or from being forced out through the openings receiving the shafts, and obviates a disadvantage in connection with the old construction of blades.

From the foregoing description taken in connection with the accompanying drawings, it is thought that a clear and comprehensive understanding of -the construction, operation, and advantages of my invention may be had, and while I have shown and described the device as elnbodying a specific structure, I desire that it be understood that such changes may be made in said structure as do not depart from the spirit and scope of the invention as claimed.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

The combination in a churn of a tubular shaft extendingtherein, a second shaft eX- tending through the tubular shaft into 'the churn, means for imparting opposite rotation to the shafts, an outer blade formed of a iiat plate connected with the tubular shaft Copies of'this patent may be obtained for and provided with oppositely curved outer side edges and with series of openings adjacent each outer side edge, said outer blade having a portion thereof between its side edges and above the lower edge out out to receive an inner blade formed 0f a fiat plate conforming` to the contour of said cut out portion, and positioned therein and connected with the second shaft, said inner blade having its side edge portions curved in opposite directions and opposite to the direction of curvature of adjacent side edges of the first mentioned bla de.

In testimony whereof, I affix my signature hereto.
